A follow-up study of 204 Harvard University graduates revealed that after approximately 40 years, the individuals who were the most "vibrant" were those who had "high salaries," were "happily married," and were "satisfied with their jobs."

The extent to which a calm mind is beneficial for health, and how much confidence and proactiveness benefit life, is beyond imagination. Why is this?
